Change History

'Inline label' is very special as we must impose a fixed size on it, since it's not able to know potentially all the possible text size within it ( text may comes from the combo options ), so it's not a bug.
You could provide your own style if you see problems with your language, e.g. :

You're not really fixing anything with this change. You're simply making the font size combo having the default width, which is 60px. Whatever attempt to remove the fixed size of these combos can make the toolbar elements start dancing depending on the size of the combo texts, which is extremely undesirable.

As explained by @fredck such cases should be handled by CSS and not by JavaScript. All that is needed here is proper document explaining how to change these settings.
I’m closing this one as DUP #6162.
